description A gripper mechanism for a downhole tool is disclosed that includes an eccentric linkage mechanism. In operation, an axial force generated by a power section of the gripper expands the linkage mechanism, which applies a radial force to the interior surface of a wellbore or passage. A sliding portion allows the gripper to slide along a surface of the formation in response to the radial force applied to the interior surface of the wellbore or passage.
